EGG 'rssrsn Filed Aug. 31, 1929 INVENTOR B HOWARD A PACKARD ATTORNEYPatented Sept. 30, 1930 UNITED STATES HOWARD A. PACKARD, or PIERCECOUNTY, WASHINGTON} Assrenon To VIACK'ARD' TESTERS, INCORPORATED, ACORPORATION or WASHINGTON EGG TESTER Application filed August 31, 1929.Serial No. 389,719.

This invention relates to improvements in egg testing devices and hasreference in particular to devices employing an electrically lightedhousing having an opening; against which the egg is placed for testingand which will be interiorly illuminated by the light from within thehousing.

It is the principal object of the present invention to providea devicethat may be made quite small as compared with devices now generally inuse, which may be easily handled, and'which is so constructed as toprovide an interior dead air space'which prevents excessive heating ofthe device and renders it easily usable. I

Other objects of the invention reside in the various details ofconstruction and in the combination of parts as will hereinafter bedescribed.

In accomplishing these objects I have provided the improved details ofconstruction, the preferred forms of which are illustrated in theaccompanying drawings, wherein Fig. 1 is a View showing, in longitudinalsection an egg tester embodying the present invention as connectedthrough a transformer with an electric circuit.

Fig. 2 is a perspective view of the parts of the tester in disconnectedrelation.

Fig. 3 is a sectional detail lengthwise of the device.

Referring more in detail to the drawings:

The egg tester is designated in its entirety by reference numeral 1, andit haselectrical connection through wires 22' with a transformer 3, andthis in turn has connection through wires 44 with an electric circuit;the transformer in this instance being employed to step down the currentso as to permit use of a very small lamp with the ordinary 210-voltlight circuit. Heretofore large lamps have been employed in suchdevicesand because of this the testers were large and cumbersome and gotexcessively hot while in use.

The present tester comprises a cylindrical outer housing 5 into whichthe circuit connections 2-2 are extended at one end; the other end beingopen and is arranged to receive therein and to contain a reflectormember 6. This has a rounded base end 2, in which an incandescentelectric lamp 7 is mounted, and the lamp has electrical connection, inthe usual way, with the circuit wires. The outer end portion of thereflector member has a peripheral flange 8 that seats Within an annularshoulder 9 that is formed at the outer end of housing 5. The arrangementand relationship of the housing 5 and reflector is such. as to leave anair space 10 between them, and this prevents transmission of heat fromthe lamp to the housing which would render it uncomfortable forhandling.

Fitted within an enlarged outer end portion 5 of the housing 5 is atubular extension 11 that terminates in a somewhat restricted outer endopening 12 about which a rubber cushioning ring 13 is fitted; thislatter serving as a seat against which an egg, as designated on dottedlines in Fig. 1, is placed when tested.

In using the device, the egg is placed against the seat and the observerinspects the egg from the side opposite the tester the light from thelatter illuminatingthe interior of the'egg to an extent sufiicient thatone experienced can determine its condition.

The present device can be easily and quickly taken apart or reassembled.It is small and compact; will not become hot to an extent that wouldrender it uncomfortable to handle. The use of the transformer makespossible the use of a small lamp and thereby cuts down the size of partsand amount of heat given. off.

It is to be understood that the proportion of parts and various detailsof construction could be changed Without departing from the spirit ofthe invention, and for this reason it is not desired that the claimbelimitedonly to the details herein shown.

Having thus described my invention, what I claim is new therein anddesire to secure by Letters Patent, is:

said. socket having an outer end enlargement forming a shoulder againstwhich the reflector seats to limit its inward movement and a tubularextension fitted at one end in said enlargement of the socket and havinga restricted outer vend opening. with a cushioning band fitted to saidopening.
